It is also used by the students to disassemble the cylinder heads with valves, the two-piece piston with its rings and wrist pin bearing, the valve rocker arm assembly, and the multi layers of the cylinder head to observe its water passages, fuel injector, and test cock mountings.
- There are a large number of engine components and parts in the training school. Many of the components are from several different manufacturers.
These components include turbochargers, scavenging blowers, pumps (fuel transfer, fuel injection, lube oil, and jacket water), cylinder head assemblies, pistons, governors, injection nozzles, duplex filters, crankshafts, connecting rods, bearings, flexible drive gears, vibration dampers. Most are cutaway which enables students to examine their internal working parts without disassembly. These Rev 3-16 2 USNRC HRTD
